Reading this question How fast does gravity propagate?, I'm curious over the consequences of the sun being removed.
As should be clear, we cannot just remove the sun as it violates energy conservation. We can however let the Sun accelerate fast (but subluminal) out of the solar system.
Assuming this (unreasonable) scenario, will this fast disappearance of Sun cause any gravitational wave signature? Basically would and experiment such as LIGO be able to measure a gravitational signature of the Sun's removal.
INTUITION: The intuition I'm having here is that if the Sun is removed quickly there could be ripples in the space-time in the wake of the Suns path out of the solar-system, and these could be detected.
